Fluoropolymer Gear Pump (FGP)

Get More from Your Process

PSI Fluoropolymer Gear Pumps (FGP) are engineered to meet the unique processing demands of fluorinated polymers, such as FEP, ETFE, PTFE, PFA, PVDF.  Manufactured from a nickel-chromium superalloy, FGP gear pumps possess excellent mechanical strength at high temperatures and are highly resistant to corrosion.  Applied primarily for tube, profile and sheet, these gear pumps offer exceptional metering control, steady die pressure and uniform gauge.  Each full revolution of the tight-tolerance, counter-rotating gears delivers a precise linear volume of output, assuring optimal efficiency across the speed range.
